Auditory sensitivity of the rhesus monkey.

Abstract

Under comparable conditions, free-field behavioral auditory thresholds were obtained from 4 simian Ss at 16 frequencies and from 7 human Ss at 14 frequencies. Human thresholds were generally slightly lower through 4 kc, while above that the simian thresholds were lower. The rhesus monkey retains good sensitivity up to at least 31.5 kc.
